NAME
       calendar - reminder service

SYNOPSIS
       calendar [ - ]

DESCRIPTION
       _C_a_l_e_n_d_a_r  consults  the  file  ‘calendar’  in the current directory and
       prints out lines that contain today’s or tomorrow’s  date  anywhere  in
       the  line.  Most reasonable month-day dates such as ‘Dec. 7,’ ‘december
       7,’ ‘12/7,’ etc., are recognized, but not ‘7 December’ or  ‘7/12’.   If
       you  give the month as ‘‘*’’ with a date, i.e. ‘‘* 1’’, that day in any
       month will do.  On weekends ‘tomorrow’ extends through Monday.

       When an argument is present, _c_a_l_e_n_d_a_r does its job for every  user  who
       has a file ‘calendar’ in his login directory and sends him any positive
       results by _m_a_i_l(1).  Normally this is done daily in the wee hours under
       control of _c_r_o_n(8).

       The  file  ‘calendar’  is  first  run  through  the ‘‘C’’ preprocessor,
       _/_l_i_b_/_c_p_p, to include any other calendar files specified with the  usual
       ‘‘#include’’  syntax.  Included calendars will usually be shared by all
       users, maintained and documented by the local administration.

FILES
       calendar
       /usr/lib/calendar to figure out today’s and tomorrow’s dates
       /etc/passwd
       /tmp/cal*
       /lib/cpp, egrep, sed, mail as subprocesses

SEE ALSO
       at(1), cron(8), mail(1)

BUGS
       _C_a_l_e_n_d_a_r_’_s extended idea of ‘tomorrow’ doesn’t account for holidays.
